This brief bilingual vocabulary (with approximately 400 entries) includes many of the most common words in the San Juan Guelavía Zapotec language (Oaxaca, Mexico). The entries in both the Zapotec–Spanish and Spanish–Zapotec sections include parts of speech and translation equivalents. Following the body of the vocabulary, there are appendices that provide focus on particular semantic domains: the ancient number system, proper names, some animal names, and pronouns.
